So I discovered some mugwort near my house and did some research, and it seems like the two major uses it had was for female reproductive things (easing period cramps, inducing a period if late, expelling dead miscarriage tissue, inducing abortions, etc), and for magickal hallucinatory derivatives (divination, trance states, inducing prophetic dreams). From what I read, the two uses seem to be separable by how much you use, but I couldn't find anything describing what point that was. I'd like to know if there's a sort of measure (even if it's in cups of tea type measurements) that is a good rule of thumb as to where the hallucinogenic properties take noticeable effect, as I would like to avoid them if trying to treat menstrual issues on their own.
As for dosage, firstly, I would suggest using it sparsely. Of the three plants in the Artemesius genus, they can become toxic at higher dosages.
All three contain a chemical called thujone, which is not hallucinogenic, but is a neural excitor. This means you may not see what's not there, but it sort of kicks the brain a bit into overdrive in a sense. Dreams will be quite vivid, for example. And yes, this also means that visualization-related work in magic can also be enhanced.
As for female reproductive help, in part this is because (I don't recall whether it is thujone or some other common chemical among the genus) mugwort is supposed to improve blood flow. I would not recommend this as a medical substitute if there are actual problems, but these plants have been used for such things for a very long time.
I have used mugwort at different times over the years to help with opening and aligning of the third eye which helps increase visions and aids divination. Though I have joint pain and have had issues with mensural pain and irregularity I have never used mugwort for these ailments.I suggest more research into the herb as well as proper dosing because without this knowledge there is potential for misuse of this herb that has been used for thousands of years for it's natural benefits and healing abilities. Below are some links to help you further in your study of this and other herbs.
In potion-making, herbalists use the root of mugwort for energy boosts (which should be avoided if a person suffers from hypertensive disorder) and the rest of the plant for different kind of stomachaches, as this plant stimulates the activity of the digestive system.
In certain cases, women prepare certain mixes and drink it for menstrual issues, as it is said that the plant helps regulate the uterine cycle.
Mugwort by itself, if ingested, has no effect over the nervous system. In certain combinations with other plants, it can help with depression, fatigue, irritability, anxiety, etc.
In order for Mugwort by itself to have a hallucinogenic effect, it is supposed to be smoked or brewed and the steems inhaled.
For what you need, I recommend the following recipe:
Place 1 ounce of dried mugwort in a cauldron. Add 4 cups of water (250 ml each cup). Let it boil for 10 minutes and avoid inhaling the steam. If you do inhale the steam, well, nothing bad will happen, but it may have a little bit of impact over your nervous system. Nothing to worry about, it is very mild.
The availability of this tea is around 3 days if you keep it in the refrigerator.
There also is a different kind of potion which is way more complex. It helps better with the kind of issues you have, regarding menstruation and the health of the female reproductive system. If you want it, tell me. I don't have time to look for it at the moment, but I will post it in a few hours if you need it.
